In 2009, we launched the DoubleClick Ad Exchange as a way to simplify the process of buying and selling display advertising, drive performance for our advertiser and publisher partners, and open up the display marketplace. In the two years since, exchange-based trading has taken off -- we’ve seen the volume of trades on our own exchange grow by more than 150% in the past year. At the same time, display, as a medium, has evolved.

Display started as just banner ads on websites, but has grown to include a range of formats as diverse as the web itself -- rich media ads that bring a page to life, in-stream ads that play before your favorite online video, and ads that run in the mobile version of your daily newspaper. To reflect this growing diversity, we have been expanding the types of formats in the Exchange. We support the most popular types of rich media ads, including units that run in-page with video, or expand when you click or mouse over them. It’s also possible to buy ads across the mobile web. Earlier this year, we announced that in-stream video formats were coming to the Exchange, and we’ve seen huge demand since launch: the number of buyers for in-stream video has tripled over the past quarter.

Today, we are announcing another step forward -- in the coming weeks, AdMob developers will be able to make their in-app inventory available on the DoubleClick Ad Exchange. Initially, a small number of pre-qualified buyers will be able to compete for this inventory. Over time, we'll be rolling it out more broadly. Ultimately, this will give app developers and publishers access to a wider pool of buyers like demand-side platforms and agency trading desks, improving their potential returns, and helping grow the overall mobile web economy. And marketers on our Exchange will be able to buy, in real time, ads that run inside people’s favorite mobile games, news apps and more. With this important addition, the DoubleClick Ad Exchange will be truly cross-format...and will become the first exchange to support this full range of ad formats.

VivaKi, one of our key partners on the Exchange, is gearing up to start buying in-app ads on the Exchange. “We are delighted to be working with Google as they open up the DoubleClick Ad Exchange to include AdMob in-app inventory, and to deliver this opportunity to our clients,” says Kurt Unkel, Senior Vice President, VivaKi Nerve Center. “We anticipate this experience will help us bring mobile to scale to our partners, and will provide insight into the operational elements and the creative assets that work best in this environment.”

A cross-format exchange is just one of the ways we’re looking to simplify the process of buying and selling display advertising, but one we think will create tremendous value for advertisers and publishers. We will continue to work with our partners to help them get the most out of what the evolving display market has to offer -- today, tomorrow, and in the years ahead.
